Measuring great saphenous vein (GSV) diameter is standard in pre-interventional assessment of varicose disorders, but has never been properly validated. This work assessed the relative value of measuring GSV diameter at the most often used sites: the sapheno-femoral junction and the proximal thigh.
The gestational sac (GS) is the first sign of early pregnancy on ultrasound and can be seen with endovaginal ultrasound at approximately 3-5 weeks gestation when the mean sac diameter (MSD) would approximately measure 2-3 mm in diameter. true gestational sac can be distinguished from a pseudogestational sac by noting: 1  its normal eccentric location: it is embedded in endometrium, rather than centrally within the uterine cavity. 2  presence of a yolk sac: seen at approximately 5.5 weeks. 3  presence of the double decidual sign (most helpful at 4-6.5 weeks).
